Commonly Problems Analysis of the Dryer

The dryer is mainly used to dry certain humidity or granularity   materials  in mineral processing, building materials, metallurgy, chemical industry and other departments.
The rotary dryer's  materials adaptability is strong, can be used to dry various materials, and the equipment is simple and reliable, so it is widely used.
In the production process, if done incorrectly,   multiple issues will appear, the following are the analysis of the commonly problems of dryer, including the problems reason and solutions.
[1] dryer raw materials fire
Reasons:
1. improper use of the dryer equipment;
2. The dryer equipment is too small to achieve the drying effect,  and force heat to cause a fire;
3 dryer equipment design principle problems;
4 the raw materials suction does not work,  which leads to the dryer in fire.
Solution:
1, consulate with the manufacturer to obtain a copy of the device manual to learn the correct way to use the dryer;
2, replace or retrofit dryer equipment;
3, require manufacturers to replace or retrofit dryer equipment;
4, check whether the dryer equipment is installed correctly ,  leaks , increase the air pressure or not.
[2] raw materials does not dry once time 
Reasons:
1, the dryer is too small;
2 wind net wind pressure, flow calculation error;
3. Dryer's improper use.
Solution:
1, increase the temperature of the dryer, but this method is easy to cause a dryer fire, the best way is to replace or modify the drying equipment.
2, based on the actual situation, ask the dryer manufacturers to provide change programs design  on the basis of re-calculating wind pressure, flow rate   .
3, consulate with the manufacturer of the dryer to obtain equipment manual to learn the correct way for using;
[4] dryer blasting
Reasons:
Dryer temperature is too high, resulting in drying equipment fire;
2, dryer equipment plugged.
Solution:
1, reduce the temperature of the dryer;
2. Clean the dryer equipment.
[5] splitter chimney material
Reasons:
1, the dryer separator is too small;
2, separator design error;
3, dryer air mesh wind pressure calculation error.
Solution:
1, replace or retrofit dryer separator;
2, negotiate with the dryer manufacturers for the settlement design;  
3, consultation with the manufacturers.
[6] materials wet and dry is uneven, system bar of the dryer machine can not work properly.
Reasons:
1, drying equipment used improperly;
2, dryer raw materials get lumps (such as the northern winter raw thawed group).
Solution:
1,  consultation with the manufacturer to obtain equipment manual to learn the correct way for using;
2, crush the lump materials ,and then dry them.
